Fantastic Quality and Lightning-Fast Shipping for Nezuko Demon Slayer Baby Costume
I recently purchased the Nezuko Demon Slayer baby costume for my little one, and I am absolutely thrilled with the experience. From start to finish, everything about this purchase exceeded my expectations. The costume itself is of exceptional quality, and the shipping was incredibly fast.

Moreover, I cannot emphasize enough how impressed I was with the shipping speed. I placed my order online, and within a matter of days, the package arrived at my doorstep. The promptness and efficiency of the shipping process were exceptional, especially considering how some other online retailers struggle with timely deliveries.

Awesome Onesie Cosplay
Omg this was so cute! All one piece. Lots of buttons at diaper, so it was a pain to close every time. True to size, and held up through washes (we’re anime fans and love dressing our kid).

Quality material and well made
Material is soft and strong. Really good quality, and so cute!! Definitely worth the price, and the size is good. It took a couple weeks to arrive however, so consider ordering a size up to make sure baby will fit. That’s what I did and it’s perfect!

9month - 12 month size
I bought this knowing it would arrive between November 4th - 12th. It ended up arriving 10/31 because the seller shipped it on Express! I couldn't be more grateful to them for getting it to us so quickly. The quality of this Onsie is soooo GOOD! I recommend it to anyone on the fence. It's too adorable I can't get enough. Size I bought is 9month - 12 months

Great Design and Feel, but Too Big
It looks exactly like the photo and matches the color. The quality of the material is nice and has a good thickness to it. I got the smallest size (0-3) and it’s huge (at least for my 2 month baby girl who’s a slightly smaller for her age). I doubt she’ll be able to wear it for Halloween this year (she’ll be 3 months), but I’ll keep in anyway because I’m a fan of Demon Slayer. My guess is that she’ll wear in at 6 months or later.

Tal como en la foto, el diseño es muy bonito, bien como mameluco completo y la capa es liviana así tiene mejor movilidad, ya que no le estorba, es cómodo al poner y al usarlo, los materiales de la tela son muy buenos es tela gruesa y la capa es delgada pero el estampado es muy bueno de ven geniales las flamas, lo compre para que mi bebé saliera con su tia que adora a rengoku. Así que ella encantada con el y mi bebé muy como con el traje. Lo recomiendo mucho. En tamaño a el le queda un poco largo y ancho pero por qué apenas tiene 12 meses y lo pedí para 18 meses, así que más que perfecto

The product is great. But i noticed after ordering this item, I received a lot of spam calls (saying something in Chinese or rather from Chinese embassy or to cancel an Amazon order)
